Original Quads (57) - the perfect amp

I’m running rebuilt late 50s EICO HF-35 monos under each speaker. They are a EL34/6L6 design (running 7581A) and sound fantastic.

Basically any 10-35 watt (more if you have protection circuit) push-pull tube amp will work. The Quads reveal more and more detail with improved equipment at every stage.

@whart I ran Quad ll in the 80s with GEC 66s too. Magical midband and sweet as a nut. However, If my aural memory serves me well, I do believe my updated EICOs may solidly outshine them.

The Music Reference RM-10 is perfect for the Quads, as is the Atma-Sphere S-30.

Thanks everyone for your responses, I really appreciate it!

Berning EA-230 works great.I am using 2 of them in mono.  Zh-270 is also great.
